Title: Composition generating microbubbles
Inventor: RASOR JULIA S
IPC: A61B10/00
Filed: 1981-11-17
Granted: 1986-02-20
Abstract: Microbubbles are formed in a liquid, e.g., blood in order to alter the transmission characteristics thereof to electromagnetic and sonic waves transmitted therethrough, by dissolving therein a solid particulate material, preferably as a suspension in a carrier liquid in which the particulate material is at least temporarily stable, the particles of which are substantially free of microbubbles and have a plurality of gas-filled voids communicating with the surface of the particles and providing nuclei for microbubble formation and the ratio of the mass of the particles to the volume of gas in the voids is sufficient to render the liquid in which the particulate material is dissolved supersaturated with respect to the gas in the voids in the area of the liquid surrounding the microbubbles when they are formed.

Inventor: BREQUE ANNE
IPC: C07F9/6568
Filed: 1981-05-26
Granted: 1986-03-13
Abstract: The phospholes and P-functional phospholes correspond to the general formula:   <IMAGE>   in which: R1 and R2 are identical or different and represent hydrogen or a lower alkyl group of C1 to C4 such as a methyl group, and R3 represents an aryl group (such as -C6H5) or a substituted aryl group (such as -CH2C6H5) or an alkyl group (such as -CH3, -C2H5, -C3H7 to C12H25) or a -(CH2)nZ group where Z denotes a function of the -COO-alkyl type (such as -COOC2H5), -CH, -CO-aryl (such as -COC6H5), -CO-alkyl (such as -COCH3) or -OH and n>/=1. At least one alkyl- or arylhalogeno phosphine is reacted with a butadiene whose carbons in the 2 and/ or 3 positions carry possibly a lower alkyl substituent, the cyclic adduct resulting from this reaction is then subjected to the action of a tertiary amine selected from among those having a pKa comprised between 5 and 11, then the product obtained is functionalized if the corresponding P-functional product is desired. Some of the phospholes thus produced are novel, particularly those of the above formula wherein R3=-(CH2)nZ such as above defined with n NOTEQUAL 2 for Z=CN.

Inventor: CUE ROBERT
IPC: B44C1/16
Filed: 1982-11-10
Granted: 1986-09-18
Abstract: The invention relates to a device for transferring a print design under action of heat from a carrier band (20) onto an object (24), in which the carrier band (20) is transported from a tape dispensing roll (1) past a scanning arrangement (5) and a preheating arrangement (6) by a drive roller (9) driven by a band drive motor (10) through a transfer zone to a band take-up reel (12). The object, in each case, to be provided with the print design is conveyed by a transport device (18) provided with holding members, a surface of the object receiving the print design as it passes into the transfer zone. The particular print design is transferred under pressure and heat from the moved carrier band (20) onto the moving surface of the object (24). For the simplification of the construction and of the manner of operation of such a device, the band drive motor (10) for the drive roller (9) of the carrier band (20) is constructed as a step motor, where the synchronization of the band drive motor (10) with a transport drive motor (15) bringing about the movement of the surface of the object (24) is accomplished electrically by a pacer (16) allocated to the transport drive motor (15).

Title: Radial shaft sealing ring
Inventor: HOLZER HELMUT
IPC: F16J15/3224
Filed: 1983-01-22
Granted: 1986-07-03
Abstract: A radial shaft seal ring has a lip ring for sealing to a shaft for rotation therewith. A U-shaped recess extends around the lip ring. An extension portion of a reinforcing ring which delimits a space on one side thereof to be sealed contacts the U-shaped recess without pressure or connection for low wear relative rotation therein. Preferably, the shoulder of the lip ring defining the side of the U-shaped recess on the sealed-space side of the reinforcing ring has a greater outside diameter than that on the other side to centrifugally aid the seal. More preferably, the latter is done by angling the U-shaped channel to the sealed side to also accommodate axial vibration of the shaft and lip ring.

Title: A packing container for pressurized contents and a method for manufacturing the same
Inventor: PALM LARS-ERIK
IPC: B65D77/06
Filed: 1983-06-06
Granted: 1987-05-27
Abstract: A packing container for pressurized contents, e.g. beer or carbonated refreshing beverages, can be manufactured from different material combinations which together provide the packing container with the necessary strength as well as the required tightness for gas as well as liquid. In accordance with the invention a packing container is formed having an outer casing which has several material layers and which provides the packing container with its strength and gas-tightness, and a liquid-tight inner container of flexible plastic material. In the manufacture and filling of the packing container, the capacity of the contents is used to give off gas so as to expand the inner container until it lies closely against the outer shell and at the same time force the air out of the casing so that the packing container is rendered completely free of air.

Patent DE-3381713-D1 (DE)
Inventor: BINGHAM JOSEPH P
IPC: H04N7/16
Filed: 1983-12-21
Granted: 1990-08-09
Abstract: In order to control subscriber access to selected television programmes in a CATV system, non-standard horizontal synchronizing pulses are generated (13, 15, 17) having a greater amplitude and either a higher or lower pulse repetition rate than the contained horizontal synchronizing pulses. These are selectively added (19 ... 23, 27 ... 33) to those television programmes to be controlled. As a result, the television receiver of a nonpaying subscriber interprets the non-standard pulses as being valid horizontal synchronizing pulses thereby preventing the receiver from synchronizing its line scanning with that of the television programme, rendering the picture produced therefrom unviewable.

Title: Double sheet detection method and apparatus of sheet-fed rotary press
Inventor: WATANABE HIDEO
IPC: B65H7/12
Filed: 1984-01-24
Granted: 1988-01-14
Abstract: Light is passed from a source through a hole in the feedboard to a photosensor which measures the light transmitted through  each sheet in turn as it is fed. Theoretical amts. of light (A,B) transmitted through single and double sheets respectively lie on either side of a theoretical reference value (Mn). This is subtracted from the theoretical single-sheet transmission (A) to obtain a theoretical difference (Ln) which is subtracted from the actual transmission to obtain an actual reference value. If this differs from the measured value, a double feed is signalled. A detectable range (DE) corresponds to transmittance variation from zero to 100%.

Title: Echo correction apparatus, particularly for a television data transmission system
Inventor: DUBLET GUY PIERRE
IPC: H04B3/23
Filed: 1984-10-09
Granted: 1988-06-23
Abstract: Echo cancellation is carried out on a received demodulated analog signal. The apparatus comprises an analog transversal filter, a computing circuit for generating the direct coefficients a1 to ar and, eventually, feedback coefficients b2 to bm of an analog transversal filter. The input of a computing circuit is connected to the input of an analog transversal filter. The computing circuit is comprised of an analog-to-digital converter, whose output is connected to a self-adaptive digital transversal filter. The values of the digital transversal filter multiplication coefficients are applied, as coefficients, to the multipliers of the analog transversal filter. The optimization criterion is that of the mean quadratic error. The convergence algorithm is that of the gradient. The iterative correction may be carried out at each step on the digital transversal filter's group of coefficients. Or, it can be carried out cyclically of each of the digital transversal filter's coefficients. Variations of the self-adaptive digital transversal filter are described.
